SPIRAL CUTTERS – MICRO-GRAIN SOLID CARBIDE

A range of 2 flute high quality micro-grain solid carbide cutters primarily
intended for use in CNC and fixed head routing machines. These
specialist cutters offer high performance routing, with fine finish and high
feed rates being prime advantages over straight flute cutters. In cases
where carbide tip tools perform well, spiral routers will cut smoother and
generally last up to 5 times longer. This extra tool life means fewer tool
changes, less setup time and longer production runs. The cutters are
suitable for use at speeds of 17,000 to 25,000 rpm and with feed rates of
6 to 10 metres per minute. It should be noted that the most common
reason for premature wear and tool failure is insufficient feed rates.
N.B. Check shank sizes carefully, as many are metric.
